LANTERN.

SPECIFICATION formingpart of Letters Patent No. 225,983, dated March 30,1880.

Application filed December 1, 1879.

To all whom t may concern:

Be it known that I, LEONARD HENKLE, of Rochester, in the county ofMonroe and State of New York, have invented a new and useful Improvementin Lanterns, which improvement is fully set forth in the followingspecification and accompanying drawings, in which- Figure lis a sideelevation; Fig.2, a vertical section of the top part of the lantern;Fig. 3, aplan of the globe-base; and Fig. 4, a central section of thelatter, as indicated by the dotted line in Fig. 3, Figs. 2, 3, and 4being drawn to a scale larger than that of Fig. l.

My invention consists in certain improvements in barn or railroadhand-lanterns', hereinafter described, and particularly pointed out inthe claims.

In the drawings, A is the globe, B the oilreservoir, C the air-supplytubes, D the cone, and F the bail, of an ordinary hand-lantern.

An ordinary cylindrical part, G, rises centrally from the oil-reservoir,upon which is f1tted the cone, said cylindrical part and cone inolosingan ordinary vertical wick-tube.

Upon the horizontal shoulder of the cone rests a circular globe-base, J,which consists, substantially, of a horizontal circular plate, b, Figs.3 and 4, provided with a central orifice fitting upon vthe cone, and twoconcentric flanges, d and h, the bottom end of the globe resting partlywithin and upon the outer ange, (l, as shown in Fig. l. The flange d isperforated with small holes c, through which air may flow to theinterior of the globe, to convey away the heat of the E'iiameijwhich maybe thrown against the interior surface of the globe when the lantern isswung about, as in railroad practice. The iiange h serves as abreak-wall to deilect the currents of air upward, as indicated by thearrows in Fig. l, and prevent their passing inwardly to the flame.

The plate b, at its inner edge, has two raised parts, c o, on oppositesides ofthe cone,"formed for the purpose of allowing air to iiow upwardover the outside of the cone to the upper portion of the flame for thepurpose of completing the combustion. (Fully shown in Fig. 4.) The inneredges of the parts c o are cut to a larger circle than the iiat sectorsof the plate b between them, togincrease thc air-openings n, formed bysaid parts or sect'ors c c.

At some little distance above the upper ends of the tubes C is secured ahorizontal oval plate, L, which supports a vertical cylindrical rim, P.

Vithin the rim l? is teleseoped another cylindrical part, O, which maybe slid up or down, as indicated b v dotted position, said part Osupporting, at some little distance above, a dome, S, upon standards g.The slide O has cut in its opposite sides two right-angled slots, c, asshown in Fig. 2, which ligure represents the top part ot1 the lantern assectioned along the line It' in Fig. 1.

j' are two pins projecting inwardly in horizontal positions from the rimP through the slots e, as shown. The rim P has a strip cut from itslower edge, about one-half way around, to form an opening, T, on oneside, to allow the top end of the globe to be swung into place, asindicated in Fig. 2. When the inner slide, O, is pressed down, it closesthe said opening in the rim P and completely surrounds andvrctains thetop endof the globe after the same has been brought to position.

The dotted position of the slide O in Fig. 2 shows the same when presseddown with its lower edge upon the bead of the globe.

Z are two inclined portions of the upper edge of the slide O, up alongwhich the pins f ride when the slide O is pressed down and slightlyrotated in the direction indicated by the arrow z'. As the pins j' slideup the inclines Z, the part O is pressed more lrmly down upon the beadof the globe, holding it securely between said part and the base-pieceJ, above described.

p p are two U-shaped pieces of sheet metal (the right-hand 011e beingpartly sectioned away) bent around the tops of the tubes C, the parallelparts of which reach to and are fastenedupon the rim P. The upper edgesofthe pieces p p are closely joined to the under surface of the plate L,their use being to prevent currents of air from passing horizontallyacross the ends of the tubes, which currents, if sufficiently strong,would extinguish the flame.

s s are two sloping roofshaped wind-guards straddling the tubes,extending a half-inch laterally out from the same, which tend to breakthe air as the lantern is swung in the direction of the plane of thetubes. x a: are similar,

IOO

but nearly vertical, wind-guards, (the righthand one being' sectioned inFig. 1,) assisting the guards s s to break the air as the lantern sswung as above. These guards correspond in width at the top to that ofthe guards s s, to which they are secured, and taper toward the bottomends to correspond to the diameters of the tubes C, to which they arealso secured, having stift'ening-tlanges turned up at right angles alongtheir edges.

t t are two vertical webs extending inwardly from .the inner surfaces ofthe tubes toward the globe, which extend somewhat'above the mouths ofthetubes, as shown at the right-hand side in Fig. l, said webs respectivelydividing equally the guards xx, above described. These webs serve tocheck and break currents of air passing horizontally through between thetubes and the globe, which currents, unobstructed, would tend toextinguish the flame by drawing the air up through the tubes. Theseseveral wind-guards, together with the plate L, completely protect theupper open ends ofthe tubes from violent currents of air proceeding fromany direction, breaking the same and permitting' the flame to draw itssupply of air from a comparative calm or statical air about the mouthsofthe tubes, whether in windy weather or during violent swinging of thelantern in use.

I claim as my inventionl. ln combination with the vertical sliding pieceO, telescoped within a band or shell, P, the said band or shell P,having a belt cut from its edge one-half around, leaving an opening, T,for the purpose of allowing the top end ofthe globe to be carried intoplace, substantialljr as shown.

2. The combination of the cylindrical rim P, having an opening, T,substantially as described, provided with pins ff, and the inner slide,O, provided with angle-slots c and inclines l, substantially as shown.

3. In combination with the pipes C G and plate L, the wind-guards p, s,t, and x, when arranged and combined substantially as described andshown.

4. The globe-base J, provided with concentric an ges h and d and acentral orifice to receive the cone, and having raised parts or sectorsc c, for the purpose of forming airopenings n n, substantially as shown.
